CARBOXYMETHYLCELLULOSE FOR ELECTRODE IN RECHARGEABLE BATTERY WITH NONAQUEOUS ELECTROLYTE, SALT THEREOF, AND AQUEOUS SOLUTION THEREOF |
摘要 |
The present invention provides carboxymethylcellulose or a salt thereof that can prevent defects such as streaks and pinholes from occurring in the obtained electrode when it is used as a binder for an electrode of a nonaqueous electrolyte secondary battery. The present invention provides carboxymethylcellulose or a salt thereof of which ratio of a dry mass A to a dry mass B is less than 50 ppm when 2 liters of a 0.3 mass% aqueous solution of the dry mass B of the carboxymethylcellulose or a salt thereof is prepared, the entire amount of the aqueous solution is filtrated through a 250-mesh filter under a reduced pressure of -200 mmHg, and the dry mass A of a residue on the filter is measured after filtration. The applications of the carboxymethylcellulose or a salt thereof are also provided. |
